"complete copy of Wikimedia Commons" = several TB of data. When wikimedia commons had 2 million files, total size of all files in it was 2 TB. Now it have 4 million files, so I assume it is about 4 TB or images. Not all of them are used in articles. > separate dump of only the necessary images?

I guess no need for tiles - every map can be replaced by single image like this: http://tile.openstreetmap.org/cgi-bin/export?bbox=14.173,49.969,14.63,50.193&scale=270000&format=png for the static wiki versions. Few queries and we are done :) Martin _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
